Harkness is absolutely not a hero--but unfortunately for him, he's
been volunteered by his village to save the world, and he quickly finds
that modern-day sarcasm is no match for ancient dragons.
Harkness, a medieval peasant with a millennial's mindset, is quite happy
to sit back and make quips while everyone else does the hard work. His
calculated laziness is interrupted when the gods send an ancient and
terrible scourge-by-dragonfire upon his village, and he is forced
(peer-pressured, really) into trying to save his fiancée from the dragon
who has kidnapped her.
When Harkness is sent by the village elder to find the one weapon that
is capable of killing the beast, his real plan is to go off on his own
and use his village's money to live the high life. This, of course,
would require ditching his two companions: Karla, an aspiring troubadour
whose passion makes up for her lack of adventuring skills, and Aldric,
whose kindheartedness does not make up for his lack of intelligence.
Harkness sees this journey as a paid vacation under the pretense of
world-saving, but it quickly turns serious when he realizes what's at
stake when he is forced to actually care about something--or at the very
least, pretend to.
